It is Honda’s Japan-market 399cc parallel-twin sportbike, updated for 2024 with sharper bodywork, Honda Selectable Torque Control, a five-inch color TFT display, and Honda RoadSync smartphone connectivity as standard.
Against the U.S.-market 2024 Kawasaki Ninja 500, the Honda brings more standard electronic equipment and a much larger fuel tank. The Kawasaki counters with a larger 451cc engine, higher published peak output, and roughly 21 kg less weight. For American buyers, however, the Ninja 500 is also the straightforward dealership purchase; the CBR400R was announced for Honda Dream dealers in Japan.

Honda described the motorcycle as a compact, manageable road-sport machine powered by a 399cc liquid-cooled DOHC inline twin. That description is important: the CBR400R is intended to be a practical, approachable middleweight sportbike, not a supersport replica or a direct replacement for Honda’s larger-displacement CBR models.
Why is it called a CBR400R instead of a CBR500R?
The displacement is primarily a Japanese-market decision. Japan separates motorcycles at the 400cc threshold for licensing purposes, with motorcycles above 400cc falling into a larger-bike licensing category. Honda therefore sells 399cc versions of related platforms in Japan while offering approximately 500cc versions in some other markets.
That does not mean the CBR400R and CBR500R are completely unrelated motorcycles. They belong to Honda’s accessible parallel-twin sportbike family, but the 2024 CBR400R should be treated as a Japan-market 399cc model, not as a global CBR500R replacement. A 2024 CBR400R was not presented as an ordinary U.S. Honda dealer model.
2024 Honda CBR400R vs. 2024 Kawasaki Ninja 500: specifications
The table below keeps the markets separate. Honda’s figures are from the Japanese launch specification, while Kawasaki’s figures are from the U.S. Ninja 500 specification sheet.
| Specification | 2024 Honda CBR400R Japan |
2024 Kawasaki Ninja 500 U.S. |
|---|---|---|
| Engine | 399cc liquid-cooled DOHC inline twin | 451cc liquid-cooled DOHC parallel twin |
| Peak power | 46 PS at 9,000 rpm | 51.0 hp at 10,000 rpm |
| Peak torque | 38 Nm at 7,500 rpm | 31.7 lb-ft at 7,500 rpm Approximately 43.0 Nm |
| Transmission | Six-speed | Six-speed |
| Published weight | 191 kg vehicle weight | 374.9 lb / approximately 170.1 kg for the ABS 49-state model; 377.1 lb / approximately 171.1 kg for the ABS 50-state model |
| Seat height | 785 mm | 30.9 in / approximately 785 mm |
| Fuel capacity | 17 liters | 3.7 U.S. gallons / approximately 14.0 liters |
| Wheelbase | 1,410 mm | 54.1 in |
| Front suspension | Not specified in the supplied Honda launch data | 41 mm telescopic fork |
| Rear suspension | Not specified in the supplied Honda launch data | Preload-adjustable rear suspension |
| Brakes | ABS standard | 310 mm front disc and 220 mm rear disc; ABS available according to trim |
| Rider electronics | Honda Selectable Torque Control, ABS, five-inch TFT, Honda RoadSync | ABS and economical-riding indicator on the listed U.S. specification; no traction control or ride modes listed for the base specification |
| Japan/U.S. launch price | ¥863,500 including Japan’s 10% consumption tax | $5,299 starting MSRP for the non-ABS version |
These numbers are useful for understanding the motorcycles’ positioning, but they are not a controlled head-to-head test. Honda publishes power in PS, while Kawasaki publishes horsepower, and the manufacturers report weight using different definitions and market configurations.
Engine performance: Kawasaki has the paper advantage
The Ninja 500 has the clear advantage in displacement and published peak power. Its 451cc parallel twin is rated at 51.0 hp at 10,000 rpm, compared with Honda’s 46 PS at 9,000 rpm from a 399cc inline twin.
The torque comparison is closer than the power numbers might suggest. Honda lists 38 Nm at 7,500 rpm. Kawasaki lists 31.7 lb-ft at the same engine speed, which converts to approximately 43.0 Nm. That points to a Kawasaki advantage in peak torque as well, but not an enormous gap for the type of everyday road riding these motorcycles target.

- High Resistance ABS Shell With Micrometrically Adjustable Strap

- Helmet Liner / Cheek Pads are Lightweight, Soft and Easily Removable and Washable
- Sleek and Lightweight Design Reduces Wind Noise
- Modular Flip-Up Function Anti-Scratch, Anti-Fog and Wide View Clear Visor
It would be inaccurate to declare the Ninja 500 definitively faster without comparable instrumented testing. No independent instrumented CBR400R road-test data was located in the reviewed research, and the different certification and reporting conventions make a direct dyno-style conclusion inappropriate. The defensible claim is narrower: Kawasaki has the stronger published peak-output specification, while Honda remains in the same accessible sportbike class.
Weight and agility: a major advantage for the Ninja 500
Weight is the Kawasaki’s most obvious numerical advantage. The U.S.-specification Ninja 500 ABS is listed at approximately 170.1 kg in its 49-state configuration, or approximately 171.1 kg in the 50-state configuration. Honda lists the CBR400R at 191 kg.
That is a difference of roughly 20 to 21 kg, although the comparison is not perfectly standardized because Honda reports vehicle weight and Kawasaki reports curb weight with separate emissions configurations. Even with that qualification, the direction is unmistakable: the Ninja 500 is substantially lighter on the published figures.
A lower curb weight can make a motorcycle easier to move around a garage, balance at low speeds, and change direction. It does not automatically prove that the Kawasaki has better handling, because suspension setup, tires, chassis geometry, ergonomics, and rider preference also matter. Still, riders who prioritize easy maneuverability will have a strong reason to look at the Ninja 500.
Electronics and equipment: Honda offers more as standard
The CBR400R wins the equipment comparison at the standard-trim level. Its 2024 refresh adds Honda Selectable Torque Control, a five-inch full-color TFT instrument panel, and Honda RoadSync connectivity without requiring a higher trim.
Honda Selectable Torque Control is particularly notable in this comparison because Kawasaki’s U.S. base Ninja 500 specification lists ABS and an economical-riding indicator but does not list traction control or selectable ride modes. That does not make the Ninja unsafe or unsophisticated; it simply reflects a simpler electronics package.
Kawasaki uses trim levels to add equipment. The U.S. Ninja 500 range included ABS, SE ABS, KRT, and 40th Anniversary variants at higher prices. Depending on the version, equipment such as a TFT display, USB charging, keyless ignition, and additional cosmetic or protective items may be included. Those features should not be attributed to every Ninja 500, especially the base non-ABS model.

If you plan to use a phone for navigation, a motorcycle phone mount may still be useful, but check bar clearance, the specific mounting location, device size, and vibration isolation before buying; RoadSync connectivity does not mean every universal mount will fit a faired sportbike.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Fuel capacity and everyday practicality
The Honda carries 17 liters of fuel, compared with approximately 14.0 liters in the Ninja 500’s 3.7-gallon U.S. tank. That gives the CBR400R a meaningful capacity advantage for commuting and touring between fuel stops.
Honda publishes two fuel-consumption figures: 28.1 km/L under its WMTC test conditions and 41.0 km/L at a fixed 60 km/h with two riders. These are laboratory or regulatory figures, not a promise of real-world economy. Traffic, speed, weather, load, tire pressures, riding style, and maintenance can all change consumption. Kawasaki’s listed U.S. specification does not provide a directly comparable figure in the supplied data, so it would be misleading to turn the Honda number into a claimed range advantage without a like-for-like test.
Seat height is effectively a draw. Honda lists 785 mm, while Kawasaki lists 30.9 inches, also approximately 785 mm. The Kawasaki’s lower weight may make it easier to handle for some shorter or less experienced riders, but neither motorcycle has a meaningful published seat-height advantage over the other.
Chassis and braking equipment
Kawasaki’s U.S. specification identifies a steel trellis frame, a 41 mm telescopic fork, preload-adjustable rear suspension, a 310 mm front disc, and a 220 mm rear disc. ABS availability depends on the selected Ninja 500 trim, with the base non-ABS version listed separately from the ABS models.
Recommended Free Tools
Honda’s 2024 launch data establishes ABS as standard on the CBR400R. Honda’s official FAQ identifies ABS on the 2024 8BL-NC65 model, and the current Honda product information continues to identify ABS on the NC65 platform. The supplied launch data does not provide enough detail to make a fair suspension-component comparison, so the Honda should not be declared superior or inferior in chassis hardware based only on the headline specifications.
Price and availability: the biggest real-world difference
Honda CBR400R
Honda’s Japanese manufacturer suggested retail price for the 2024 CBR400R was ¥863,500, including Japan’s 10% consumption tax. Honda’s domestic annual sales plan was 1,300 units.
That yen price is not a U.S. MSRP. It does not include international shipping, import duties, registration, possible compliance work, exchange-rate changes, or the costs associated with finding parts and service for a Japan-market motorcycle. The 2024 CBR400R was announced for sale through Honda Dream dealers in Japan, not through ordinary American Honda dealerships.

Kawasaki Ninja 500
The 2024 U.S. Ninja 500 started at $5,299 for the non-ABS version. Kawasaki also announced ABS, SE ABS, KRT, and 40th Anniversary versions at higher prices. Exact equipment and pricing varied by trim, so buyers need to compare the specific version rather than treating every Ninja 500 as an identically equipped motorcycle.

One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchFor a U.S. buyer, the Ninja 500 is therefore the much simpler purchase. It has a U.S. MSRP, U.S.-market trims, and an established route through Kawasaki’s dealer network. A CBR400R may still appeal to an importer or enthusiast who specifically wants the Japanese 399cc package, but availability and ownership logistics become part of the purchase decision.
Which one should you choose?
Choose the Honda CBR400R if:
- You are buying in Japan or have a legitimate, well-understood import route.
- You value standard traction control, a color TFT display, and smartphone connectivity.
- You want the larger 17-liter fuel tank.
- You prefer Honda’s Japan-market 399cc licensing-category package.
- You are willing to verify parts, service, registration, and warranty arrangements before importing.
Choose the Kawasaki Ninja 500 if:
- You are shopping in the United States and want a normal local-dealer purchase.
- You prioritize lower published weight and higher published peak output.
- You want the option of a lower starting price with the base non-ABS model.
- You prefer to select equipment through ABS, SE, KRT, or special-edition trims.
- You want a motorcycle with U.S.-market documentation and support rather than an imported Japan-market model.
Regardless of which motorcycle you choose, budget for a properly fitted motorcycle helmet and protective riding gear. The CBR400R and Ninja 500 are approachable middleweight motorcycles, but their sportbike riding position and performance still warrant full protective equipment.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Import and ownership checklist for the CBR400R
A Japan-market CBR400R should be evaluated as an import, not simply as a cheaper or smaller CBR500R. Before committing to one, confirm the following:
- Exact model identification: Verify that the motorcycle is the 2024 8BL-NC65 parallel-twin CBR400R and not a later E-Clutch model or another CBR variant.
- Registration and compliance: Check the rules in the destination country or U.S. state before paying for shipping. Import eligibility, emissions requirements, lighting, documentation, and registration procedures can vary.
- Service documentation: Obtain the 2024 Honda CBR400R owner’s manual and use the model-specific service information rather than assuming that every CBR500R procedure, part, or specification transfers directly.
- Parts support: Confirm how readily consumables, bodywork, electronic components, and model-specific replacement parts can be sourced in your market.
- Recall status: Honda issued a June 19, 2025 fuel-pump recall covering specified NC65 CBR400R units. Owners and importers should check the motorcycle’s VIN and Honda’s applicable recall information rather than assuming every NC65 is affected or unaffected.
- Connectivity compatibility: Confirm that Honda RoadSync functions with your phone, operating system, and local service availability. A smartphone feature is not a substitute for checking navigation and communication requirements before a long ride.
- Chain maintenance: Both motorcycles use chain final drive. Follow the owner’s manual and lubricant-label instructions; a motorcycle chain cleaner and lube is a legitimate routine-maintenance purchase, but no chain product should be treated as a guaranteed performance upgrade.
Do not confuse the 2024 bike with Honda’s later CBR400R developments
Current-status clarification: Honda’s later Japanese CBR400R information shows an E-Clutch version with 2026 specifications. That is a subsequent development and should not be used to rewrite the original 2024 launch specification.
Honda also announced a separate CBR400R FOUR E-Clutch for Japanese release on September 18, 2026, using a new 399cc inline-four engine. That future or subsequent four-cylinder product is distinct from the 2024 CBR400R’s 399cc parallel-twin engine. It is not evidence that the 2024 motorcycle had an inline-four engine or E-Clutch equipment.
The later status also matters for used-bike shoppers: a listing described simply as a CBR400R may refer to different model years and equipment packages. Confirm the engine configuration, model code, production date, and equipment before comparing prices or ordering parts.

Final assessment
The 2024 Honda CBR400R makes the strongest case for itself through equipment and market-specific practicality. It combines a manageable 399cc twin with standard traction control, a five-inch TFT, RoadSync connectivity, ABS, and a 17-liter tank. The Kawasaki Ninja 500 is the more compelling numerical and commercial choice for many U.S. riders: it has a larger engine, higher published peak output, substantially lower listed weight, a lower starting MSRP, and normal local availability.
So the answer depends less on a simplistic winner and more on where and how you will buy. In Japan, the CBR400R is a logical 400cc-category sportbike with a generous standard equipment list. In the United States, the Ninja 500 is the realistic rival and the easier ownership proposition. Calling the Honda a global CBR500R replacement, or treating the two prices as directly interchangeable, misses the reason the CBR400R exists.

Was the 2024 Honda CBR400R sold in the United States?
The 2024 launch was for Honda Dream dealers in Japan. It was not presented as an ordinary U.S.-market Honda model, so American buyers should not assume they could order one through a normal Honda motorcycle dealer.
Is the Honda CBR400R the same motorcycle as the Honda CBR500R?
They are related accessible parallel-twin sportbike models, but the 2024 CBR400R is a Japan-market 399cc motorcycle. It is not simply the U.S.-market CBR500R under a different name, and its 399cc displacement reflects Japan’s licensing structure.
Does the 2024 CBR400R have traction control?
Yes. Honda Selectable Torque Control was added as standard equipment for the 2024 update. ABS, a five-inch full-color TFT display, and Honda RoadSync connectivity were also standard in the Japanese launch specification.
Which is lighter, the CBR400R or Ninja 500?
The Ninja 500 is lighter on the published figures. Kawasaki lists the ABS model at approximately 170.1 to 171.1 kg depending on emissions configuration, while Honda lists the CBR400R at 191 kg. The manufacturers use different weight-reporting definitions, so the difference is directionally useful rather than a laboratory comparison.
Which motorcycle has more power, the CBR400R or Ninja 500?
The Ninja 500 has the higher published peak-output figure: 51.0 hp at 10,000 rpm versus Honda’s 46 PS at 9,000 rpm. Because the manufacturers use different output units and testing conventions, that specification alone does not establish a tested acceleration or top-speed winner.
The Bottom Line
Bottom line: The 2024 Honda CBR400R is Japan’s well-equipped 399cc sportbike, not a U.S.-market CBR500R replacement. It beats the Ninja 500 on standard electronics and fuel capacity; Kawasaki wins on listed weight, peak output, starting price, and U.S. availability. Buy the Honda for its Japan-specific package and equipment, and choose the Ninja 500 if straightforward American ownership matters most.
